An SRV record is a DNS record, that is used to forward a domain to a third-party server and use it for a service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is created, you are able to specify an Internet Protocol that the domain address will use and the port, which is to be used to connect to the remote server. Additionally, provided that you have many SRV records for the exact same service, you could set various priorities and weights for each one of them, so that you can spread the load between many machines. Such a record allows you to use the same domain name or subdomains under it with different providers, so you could employ it for various purposes even if you are not able to get all of the services from one service provider.
